With reference to your impressive research "Sevoflurane: Impurities and stability testing"
We report an impurities and stability testing study on two different batches of three different commercial formulations of sevoflurane, the widely used fluorinated inhalation anesthetic agent. Our analyses focused on identifying the starting presence of volatile impurities as well as the formation of degradants after storage also under accelerated ageing conditions. We found that the analyzed samples show differences in quality and quantity of impurities as a likely consequence of the different manufacturing processes. Impurities may vary from one batch to the other of a given formulation, but in all case they are well below limits specified by regulatory agencies for clinical use, the content in sevoflurane being always > 99.99%. Fluoride anion concentrations were below 0.1 mg/L in all analyzed samples, consistent with no degradation occurring in the examined timeframe.

We cordially invite you to deliver a speech on your latest research findings at the 10th Global Conference on Materials Science and Engineering (CMSE 2021) (http://www.cmseconf.org/) which will be held Online via Microsoft Teams on August 1-4, 2021. The conference is supported by the Pisarenko Institute for Problems of Strength, National Academy of Sciences of Ukraine.

** As an annual conference since 2012, CMSE has attracted more than 1400 participants from over 50 countries in the past 9 years;
** Presenters will get the opportunity to win the best presentations and be awarded free registration to CMSE 2022.
** It provides a great chance to further expand your academic networks and refresh your knowledge in related fields;
** Accepted full papers will be published in the conference proceedings (Scopus/Compendex indexed), selected papers can be recommend to ISI indexed journals.

If you are not available to join the conference, could you help us to review some papers? Active Reviewers are candidates for Technical Program Committee next year. If yes, please kindly send us your CV or let us know of your specific research interests. Thanks.

Notice: Pre-recorded video presentations are also welcomed. Video presentations from CMSE2020 can be viewed freely at the conference official website.
